Use cases • Can we slim from function up to process? • Can we infer annotations to process from those to function?

Process has_part polyamine biosynthesis urea cycle has_function Function has_part cannot be used for slimming. No Gene products Gene product y Gene product x
Can we infer annotations to process from those to function? • No. There is too much variation in process details, • and too many functions are shared.
Process phosphorylation part_of Function kinase activity We can make relationships between single step processes and their respective functions.
Process glucose transport part_of Function glucose transporter activity We can make any obvious relationship where part_of holds, and this will allow useful slimming.
We can mine the other links from pathway databases and make non-curated sometimes_part_of links.
sometimes_part_of What does this buy us? Very full coverage of function-process links. No manual link curation. What work does it involve? We maintain the mapping files e.g. reactome2go. We write the mining scripts.
